Halloween Scare using 12F683 and ISD2532
https://www.electronics-lab.com/project/halloween-scare-using-12f683-and-isd2532/
Introduction Halloween is coming up and it’s time to do some pranks. Everyone likes Halloween and I’m no exception. Every year me and my wife decorate the house with lot’s of bugs, spider webs, creepy posters and of course lot’s of Halloween candy. While making the normal Halloween preparations I came up with the […]
Hand Steadiness Tester
https://www.electronics-lab.com/project/hand-steadiness-tester/
Introduction The Hand Steadiness Tester is a game which tests the steadiness of your hand. The player has to take the ring from one end to another end without touching it to the wire. In this the player gets 4 turns. If the player touches the wire 4 times he has to reset the game […]
Bomb Game
https://www.electronics-lab.com/project/bomb-game/
Introduction “Should I cut the blue wire… or the red…?” This is a very common phrase in many movies when the action hero has a bomb in front of him with little time left and he has to choose which wire to cut and stop the bomb from exploding saving millions of people. This game […]
Motion Activated Led Dice
https://www.electronics-lab.com/project/motion-activated-led-dice/
Introduction I’ve always wanted to build an electronic led dice, but something different from what we see on the internet. Making it motion controlled… now that’s new! Many new cell phones that have accelerometers built in also have dice games. These dice move when shaking the cell phone. My Led Dice project will also […]
LED effects
https://www.electronics-lab.com/project/led-effects/
Introduction This project I made for my little daughter. It is 24 channel light illumination. The schematic is very simple 24 LEDs, 1 MCU and some additional components. The main principle is dynamic indication, which is usually implemented for control of 7-segment digital indicators. Here is the same, as for indicators are used […]
6V Ultra-Bright LED Chaser
https://www.electronics-lab.com/project/6v-ultra-bright-led-chaser/
General This is a spectacular but completely useless project. It lights Ultra-Bright LEDs in a sequence and each LED flashes brightly very briefly. The LEDs light-up going around and around since they are mounted in a circle (on a CD), then they pause before chasing again. The very brief flash of each LED (15ms) and […]
High Power LED mood Lamp
https://www.electronics-lab.com/project/high-power-led-mood-lamp/
Introduction In this page we will introduce a great project designed by Toon Beerten. His project named “DIY Led Mood Lamp” can become a very interesting add-on for your room that’s absolutely sure it will impress everyone. As you can see on the photos, we talk about a color fading lamp, that looks amazing! The […]
3V LED Chaser
https://www.electronics-lab.com/project/3v-led-chaser/
General There are many 9V chaser circuits that seem to waste about 7V when driving LEDs that are only about 2V. This project is unique, because it uses only two inexpensive alkaline battery cells totaling 3V for power. Since most of the waste is eliminated, the cells last a long time. Unlike the other circuits, […]
Motorcycle Universal Gear Indicator
https://www.electronics-lab.com/project/motorcycle-universal-gear-indicator/
Introduction This is a new design for a universal gear indicator that can be fitted to any motorcycle as an aftermarket accessory. Its main advantage is that its operation depends entirely on the gear shift lever movement, instead of connecting to speedometer and tachometer sensors (found in expensive commercial devices), which are rarely available in […]
PIC16F84A discolight effect with bass beat control
https://www.electronics-lab.com/project/pic16f84a-discolight-effect-with-bass-beat-control/
This is an early picture of my discolight effect. Because of the AGC circuit theres no need for potentionmeters for sensitivity adjust. I replaced them with trimmers. Now the microphone is on the control electronics because theres no need to place it outside the box and the possible noises from the surroundings are reduced. You […]
